A Brief Introduction to Planetary Gear Motors

Gears are one of the oldest pieces of mechanical equipment that dates back thousands of years. The first description of gears, however, was written by Aristotle in the 4^th century B.C. And sketches of various types of gears were found in Leonardo da Vinci's notebooks. Gears have come a long way since the earliest wooden models and today they are made with maximum precision and they are part nearly any machine. Gears are used to transmit power from one part of a machine to another. Buy combining them together in different ways, you can increase speed, increase force, change direction, and so on. Although they seem complex at first glance, in principle, they are actually quite simple. It's just a matter of physics in action. Let's take a car engine as a simple example. Thanks to gears, a car engine can harness the power stored in gasoline. Basically, gasoline explodes and moves the cylinders of the engine up and down. Gears make sure that this up and down motion is converted to circular motion that gets the car moving.
